php
Just a quick question – and I’m sure really basic!I have the following code:function checkThings($foo, $bar) {…if ($valid) {return $results;} else {return false;} }On the other end of this I am currently doing$check = checkThings($foo, $bar); if ($check === false) {echo “Error”; } else {echo $check; }Is writing the following the same?$check = checkThings($foo, $bar); if (!$check) {echo “Error”; } else {echo $check; }Which method is the preferred method if both are correct?Thanks 🙂

few days ago I started to work on my own WebServices. I decided to use WSO2 WSF/PHP framework and according to http://wso2.org/project/wsf/php/2.0.0/docs/manual.html created my first helloService.

php class object variable-variables
Is something like the following possible in PHP?$blah = ‘foo1’;class foo2 extends $blah {//… }class foo1 {//… }This gives an error.I want to dynamically set $blah so I can extend whatever class I want.Edit: The reason for wanting to do this because I wanted to use a function out of another class in a related class. In the end it would have been something like:Final extends foo1 extends foo2 extends foo3 extends foo4 extends parent { … }In the end I decided to instantiate the other class wi

php rets
Am a trying to create a PHP (PHrets) script that downloads all real estate listing information from a specific area and saves all of the listings data (CSV file and photos) on my web server. Note: A single listing may have up to 20 photos.I am using PHrets to retrieve MLS listing data and it works great for creating a CSV of data. However, I would like to modify this code to loop through each listing’s photos and download them onto my web server with the following name convention: MLSID-PHOTOID.

php zend-framework phpunit zend-session
I am getting numerous errors exactly like this one:Zend_Session_Exception: Session must be started before any output has been sent to the browser; output started in /usr/local/zend/share/pear/PHPUnit/Util/Printer.php/173When running my application’s test suite. This is with PHPUnit 3.5.10 and PHP 5.3.5.There is no mysterious, unexpected whitespace output that is causing this. I’ve determined that the “output being sent to the browser” is the actual output from the PHPUnit tests being executed.

java php regex pcre
In PHP and Java, I applied /^[^\pL]*|[^\pL]*$/ to ???-A- and I got *A**. I applied a symmetric pattern and got an asymmetric result! Why? I wonder why its output is not *A*?Pattern says that every thing except letter in the end of string should be replaced by *, it’s also greedy and should replace all non-letter stuff together.Alos note in RegexBuddy I get *A* that is what I expect.Update: I simplified the question to focus my main concern.

php oop class
I want to make a PHP class, lets say Myclass.php. Now inside that class I want to define just the class itself and some instance variables. But all the methods must come from a Myclass_methods.php file. Can I just include that file into the class body?I have good reasons why I want to seperate this. In short, I’ll have a backend in which I can change the business logic of a class, while all other things must remain untouched. The system maintains all the ORM and other stuff for me.But if this is

database performance oracle indexing
I have a process that is performing badly due to full table scans on a particular table. I have computed statistics, rebuilt existing indices and tried adding new indices for this table but this hasn’t solved the issue.Can an implicit type conversion stop an index being used? What about other reasons? The cost of a full table scan is around 1000 greater than the index lookup should be.EDIT:SQL statement:select unique_key from src_table where natural_key1 = :1 and natural_key2 = :2 and natura

I’ve just created a database, the first table, added one row there and now configuring Hibernate.However, even the simplest query:Criteria criteria = session.createCriteria(Place.class); List result = criteria.list();could not be executed (empty list is returned though there is one record in the database).

mysql ruby-on-rails database sqlite
After much googling I have been wondering what the benefits/differences are between mysql and sqlite3. I am primarily hoping for a speed bump when moving my development database to my production database, although I imagine this will primarily happen in my code. Does any know what the major differences are in performance? ARE there? Or would you be able to point me in the direction of some literature comparing the two?

I’ve got a problem with an update of an SQLite database in iOS7.

android database sqlite
I develop and maintain a Google Tasks app on Android. Currently I have a class that contains lists and tasks, in order, in an ArrayList. I’m thinking of switching to SQLite to better structure the app. I’m not sure what the best and easiest way to store the order of tasks in the database would be though.Right now, I can simply remove and add items at different indices and obviously the other List rows indices are in correct order. With an SQLite database, I can store a positional number in each

ios sqlite sqlite3 fmdb
I’m having some trouble dropping an index I’ve created in SQLite in an iOS application. I’m using fmdb.When attempting to drop an index, sqlite3_step always returns SQLITE_LOCKED. As a result, fmdb gets caught in an infinite loop where it continuously attempts to retry the drop statement (every single time, sqlite3_step returns SQLITE_LOCKED), and the statement never succeeds.As far as I know, there are no other processes touching the database and statements right before the drop statement work
